Sect. 1. Ingastrum. — Legume compressed. 

 * Flowers in umbels. 



256. I. heterophylla, W. Glabrous ; leaflets 1-4-jugal, elliptical or ovate-lanceolate, 

 abruptly acuminate, shining: petiole naked: glands small, cylindrical; umbels shortly pe-

 long, black when dry ; corolla 3'" long ; legume 4" long, 1" broad : margins slightly 

 thickened. — Hab. Trinidad!, Or., in mountain woods; [Guiana!, Para!]. 



** Flowers in elongated spikes or spiciform racemes. 



257. I. laurina, W., Benth. ! Glabrous; leaflets 2-1-jugal, elliptical or elliptical- 

 oblong, with a bluntish point, shining : petiole naked: glands minute, scutellate ; flowers 

 spreading, in elongated, spiciform racemes : pedicels very short, shorter than the calyx ; 

 corolla glabrous, infundibuliform, four times as long as the calyx, equalling the stamina! 

 tube ; legume glabrous, oblong, flat-compressed, somewhat tumid at the seeds. — Jacq. Amer. 

 Pict. t. 247. — Mimosa, Sw. M. fagifolia, Jacq. : erroneously quoted as I. marginata, IF. —

 spikes ; corolla strigose, twice as long as the puberulous calyx, including the staminal tube ; 

 legume . . . . — Mimosa cornscans, Sieb Mart. 324; Trin. 120. — Nearly allied to the pre- 

 ceding. My description refers to Imray's plant. The synonyms and other localities want 

 confirmation by new comparison. Leaflets 5"-2" long, narrower than in the preceding,
